2017 Porsche 911 Turbo First Drive [w/video]

Remember when turbos were a big fat middle finger to the naturally aspirated status quo? The horsepower renaissance has seen the forced induction phenomenon go from badass add-on (Turbo 'Vette!) to battle cry for efficiency (Kia Optima Turbo). From econoboxes to high-end holdovers like Ferrari and Aston Martin, everybody's doing the turbo shuffle. But what does that mean for the gang from Stuttgart – and more importantly, the top-of-the-line 911 that has called itself Turbo since the mid-1970s? I spent a day in the 2017 Porsche 911 Turbo and Turbo S to find out. Now is a particularly fitting time to evaluate the latest iteration of the venerable Porsche 911 Turbo. Our scrutiny comes at a moment when standard-issue Boxsters, Caymans, and Carreras have finally adopted turbocharged platforms. The Turbo S has a top speed of 205 mph, marking the first time the model has crested the 200-mph barrier. Spoiler alert: Rather than radically transforming its long-evolved essence, the 2017 Porsche 911 Turbo has made incremental changes that makes it, well, more Turbo than ever. Horsepower for the Turbo and Turbo S climbs 20 each, to 540 and 580, respectively; 0-60 times drop to a scant 2.9 and 2.8 seconds, and these top dogs now have terminal velocities of 198 and 205 miles per hour, marking the first time the model has crested the 200-mph barrier. The forced-induction flagships have different engine hardware, another first for the lineup, with the S gaining larger turbo impellers and housings. A revised differential enhances the precision of power transfer, while the PDK dual-clutch transmission (the only gearbox available) gains a centrifugal pendulum for smoothness. The dynamic engine mounts now work harder for crisper response, and the variable damping rates have been extended at both ends for a wider range of settings. If you're a fan of hanging the tail out, you'll be pleased to know that a new Sport mode enables greater yaw angles. And if you dig indiscreet bursts of acceleration, there's now a Dynamic Boost function that preps the drivetrain for a little extra oomph by dropping down a gear and holding the throttle open to maintain turbo pressure, increasing torque from 487 to 523 pound-feet, and from 516 to 553 lb-ft in the S. Standard equipment now includes a Sport Chrono Package, camera-equipped parking sensor, and the Porsche Dynamic Light System. Engine flexibility is outstanding, allowing peak torque to start at only 2,250 rpm.

2014 Porsche 911 Turbo Cabriolet spotted testing in the nude

The Porsche 911 wouldn't be the Porsche 911 unless there were twenty-something different models to choose from (note: we are not complaining), and the latest one was just spied by our trusty photographers out on Germany's Nürburgring. Feast your eyes on the 911 Turbo Cabriolet - the droptop version of the new Turbo wonder that debuted in May - looking all sorts of stealth in its black-on-black-on-black prototype scheme.
Mechanically, the 911 Turbo Cab should be identical to the fixed-roof version, meaning a twin-turbo 3.8-liter flat-six engine will live in the car's rump, putting out something like 520 horsepower. Of course, there's also the hotter Turbo S version of the coupe, and we expect that to get the droptop treatment, as well, with 560 horsepower on tap. The added weight of the folding top and additional structural supports will likely make for slightly slower 0-60 times for both cars, though considering the base Turbo will hit 60 miles per hour in 3.2 seconds, "slower" is a very relative term indeed. All that force will run to the ground via all-wheel drive, managed by Porsche's seven-speed PDK dual-clutch transmission.
The wide stance of the 911 Turbo Coupe carries over to the Cabriolet, no doubt fitted with the same (standard) 20-inch wheels. Inside, the usual luxury amenities will be on hand, along with nearly endless customization options.

Porsche 911 Aerodynamic prototype cheated the wind ahead of its time

You might think that sports cars would have the lowest drag coefficient of all cars. And yes, they do tend to be more slippery than, say, SUVs or convertibles, but the sleekest vehicles on the road tend to be EVs, hybrids and luxury sedans. Sports cars, on the other hand, have aerodynamically detrimental needs for downforce and additional engine cooling. Still, the Porsche 911 is better than most, and has only gotten more so over the years. Its relatively narrow track and compact form mean it has a smaller frontal area than some other sports cars, and the gradual sweeping back of its headlights and windshield have only augmented its capacity for cheating the wind.
This 911 prototype, however, is even more aerodynamic than most. It's based on a "G model" 911 from 1984, but employed such features as covered wheels, a new rear spoiler and a reprofiled front end to drop its drag coefficient from 0.40 to 0.27, making it as slippery as a modern sedan and better at cheating the wind than just about anything built up to that point, save for maybe the Tatra 77, Citroën SM or Tucker Torpedo.
Elements of this prototype ended up gradually making it into production Porsches for years to come, and you can clearly see early influences on the second-generation 964 and even on the 959. It's featured here as the latest installment in a video series on rare historic Porsches unearthed from the company archives, following previous clips that featured a rare V8-powered 911 and a mid-engined 911 prototype.
